Here's my q: * He advised wiping dew/condensation off the window sills

deteriorating the new job. (This is So. Calif coastal).

I don't understand why that is necessary, though I will do it if this
distinguished body so advises.
My thought was that the dew/condensation will evaporate anyhow when
the sun hits it.

Your thoughts?

Odds are he has seen some problems in the past. To be sure, why not
call B-M customer service and ask them? It may be that latex paints of
today develop water resistance rather slowly as they cure (as opposed
to 'dry'). Water from any source then will affect the bond to the
substrate. With that information, seems sensible to help the new
finish get extra life. HTH
